Boyd’s Bible Dictionary:
(two rivers). The alluvial plain through which the Tigris and Euphrates pass, and probably inclusive of Babylon and Mesopotamia (Gen. 10:10; 11:1-9; Isa. 11:11; Dan. 1:2). It was the seat of the kingdom founded by Nimrod, and which reckoned among its cities, as beginnings, Babel, Erech, Accad, and Calneh (Gen. 10:9-10). Asshur went forth from Shiner to found Nineveh (Gen. 10:11). It was in the plain in the land of Shinar that the migrating nation undertook to build the tower of Babel, and where the confusion of tongues occurred (Gen. 11:1-9).
Concise Bible Dictionary:
Ancient name of the plain lying in the south between the Euphrates and the Tigris. It was where Nimrod established his kingdom, and where the tower of Babel was built. Amraphel, king of Shinar, was one of the four kings who fought against the five kings when Lot was taken prisoner. In later times it was known as Chaldea, or Babylonia (as in the LXX of Isaiah 11:11), and thither some of the captives from Judah were carried (Gen. 10:10; Gen. 11:2; Gen. 14:1,9; Isa. 11:11; Dan. 1:2; Zech. 5:11).
